Fact:
A mortician gives a person their very last bath.
They must wash and disinfect the body.
They are also responsible for washing the hair and styling it.
They are also makeup artists to the dead.
They ensure that the dead they are caring for is treated with the utmost respect.
Sometimes, in the worst cases, the only time the dead has ever received kindness, was by their Mortician.
This is what I am in school for- dual licensing in being a funeral director and an embalmer.
Human decomposition begins around four minutes after a person dies and follows four stages: autolysis, bloat, active decay, and skeletonization.
Stage One: Autolysis
The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture. The membranes release enzymes that begin eating the cells from the inside out.
Rigor mortis causes muscle stiffening. Small blisters filled with nutrient-rich fluid begin appearing on internal organs and the skin’s surface. The body will appear to have a sheen due to ruptured blisters, and the skin’s top layer will begin to loosen.
Stage Two: Bloat
Stage two of human decomposition consists of bloating to the body. Leaked enzymes from the first stage begin producing many gases. Due to the gases, the human body can double in size, giving it that bloated look.The sulfur-containing compounds that the bacteria release also cause skin discoloration. In addition, insect activity can be present.
The microorganisms and bacteria produce extremely unpleasant odors called putrefaction. These odors often alert others that a person has died, and can linger long after a body has been removed.
Stage Three: Active Decay
Fluids released through orifices indicate the beginning of active decay. Organs, muscles, and skin become liquefied. When all of the body’s soft tissue decomposes, hair, bones, cartilage, and other byproducts of decay remain. The cadaver loses the most mass during this stage.
Stage Four: Skeletonization
Because the skeleton has a decomposition rate based on the loss of organic (collagen) and inorganic components, there is no set timeframe when skeletonization occurs.

Did you know that psychologically a funeral is one of the last steps of closure for families and friends after a person dies?
Everyone processes death differently. They go through the motions of grief (denial, anger, bargaining, depression, acceptance) and most people are in a state of denial when death happens- particularly in cases of violent or sudden deaths- and a funeral/wake can bring the reality of the death to the forefront for them to deal with.
It doesn't end the grief process- many still have lots of work to do afterwards, but a funeral aids in setting the situation into reality when up until that point most are unable to process everything before them. Some people go through the motions and don't accept the fact the person is dead, until they physically see them within the casket.
